Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of dust removal equipment, and in particular relates to an intelligent dust reduction device for a construction site. Background Art
[0002] As the population grows, people need more housing to meet their living needs. Construction can create various types of housing, such as apartments, villas, and affordable housing, providing people with a safe and comfortable living environment. The construction process generates a large amount of dust. Operations such as earthwork excavation, material loading and unloading, and concrete mixing all raise dust. Construction workers are exposed to high concentrations of dust for long periods of time and are prone to inhaling large amounts of dust particles. These particles will settle in the respiratory tract and lungs, and long-term accumulation may cause respiratory diseases. If this dust is not controlled, it will enter the atmosphere, causing air pollution and affecting the surrounding air quality. Therefore, workers usually set up a sprinkler system at the construction site, spraying water into the air in a mist form through atomizing nozzles. This causes dust particles to combine with the water mist, increase their weight, and settle to the ground, thereby achieving the purpose of dust reduction.
[0003] Existing atomizing nozzles are usually installed at fixed points, and their water spray is distributed in a cone or fan shape. The horizontal coverage radius of a single nozzle is small, making it difficult to form a uniform water mist layer over a large area, resulting in unsatisfactory dust suppression effect. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an intelligent dust reduction device for construction sites.
[0005] The technical solution adopted to solve the above technical problems is: an intelligent dust reduction device for construction sites, including a dust reduction installation box, a detachable water flow pushing mechanism is installed on one side of the dust reduction installation box, a linkage mechanism is provided under the dust reduction installation box, and a spray adjustable mechanism is provided under the linkage mechanism; a rapid current mounting plate is fixedly installed in the dust reduction installation box, and a plurality of groups of flow grooves are evenly fixedly connected to the circumference of the lower end of the dust reduction installation box; a mounting column is fixedly installed at the lower end of the spray adjustable mechanism, a support frame is fixedly connected to one side of the mounting column, and a reinforcing rib is fixedly connected to the support frame, and the spray adjustable mechanism can spray outward to blow away the accumulated water mist, keep the working area relatively dry, and reduce the problems of slippery ground and equipment corrosion caused by accumulated water.
[0006] Through the above technical solution, the setting of the rapid flow mounting plate can concentrate the water flow to the effective action area of the fan blade installation, so that the impact force of the water flow on the installation fan blade is more concentrated. The setting of the rapid flow mounting plate divides the space inside the dust reduction installation box into the space with the fan blade installed at the upper end and the space without the fan blade installed at the lower end. When the water flows into the dust reduction installation box, due to the setting of the rapid flow mounting plate, the tangential water flow input by the liquid inlet pipe can be further converged to the effective action area of the fan blade installation (that is, the upper end space of the blade facing the water), and the water flows into the dust reduction installation box in a tangential shape. , it can naturally form a high-speed concentrated fluid beam, directly impacting the blades of the installed fan blades, thereby maximizing the conversion efficiency of the water kinetic energy into the rotational kinetic energy of the installation shaft. After that, the water flow will naturally flow into the lower end of the dust reduction installation box through the gap between the rapids mounting plate and the mounting shaft, thereby enhancing the rotational power of the installation shaft; and the reinforcement ribs can increase the overall strength and rigidity of the support frame, so that it can withstand greater external forces and loads, and by dispersing and transmitting the forces, it can avoid deformation, bending or even fracture of the support frame when subjected to greater pressure, tension or torsion, thereby ensuring the stability and safety of the structure.
[0007] Furthermore, the water flow pushing mechanism includes an installation shaft rotatably connected to the dust reduction installation box, and multiple groups of installation fan blades are evenly fixedly installed on the circumference of the installation shaft. A liquid inlet pipe is fixedly installed on one side of the dust reduction installation box, and the liquid inlet pipe is fixedly connected to a first connecting seat at one end away from the dust reduction installation box. A second connecting seat is fixedly installed on one side of the first connecting seat, and a liquid outlet pipe is fixedly connected to the second connecting seat. The liquid outlet pipe is connected to the water tank outlet pipe, and the first connecting seat and the second connecting seat are fixedly connected by multiple groups of fixing bolts.
[0008] Through the above technical solution, the water flow propulsion mechanism uses the energy of the water flow to drive the installation shaft to rotate, converting the kinetic energy of the water flow into the mechanical energy of the installation shaft, and then driving the connection box and multiple atomizing nozzles to rotate, effectively utilizing water flow resources without the need for an additional power source.
[0009] Furthermore, the liquid inlet pipe and the dust reduction installation box are interconnected, and the liquid inlet channel of the liquid inlet pipe and the dust reduction installation box are arranged in a tangent structure.
[0010] Through the above technical solution, the water flow input by the liquid inlet pipe can enter the dust reduction installation box through the liquid inlet, and since the liquid channel and the dust reduction installation box are in a tangent structure, the water flow entering the dust reduction installation box can drive the linkage mechanism to rotate.
[0011] Furthermore, a mounting base is provided at the lower end of the mounting column, the mounting base is fixedly connected to the mounting column, and a counterweight is installed on the mounting base.
[0012] Through the above technical solution, the counterweight block increases the weight of the mounting base, thereby lowering the center of gravity of the entire device. The lower the center of gravity, the more stable the object. When subjected to external force, the device is less likely to tip over or shake, thereby improving the overall stability of the device during use.
[0013] Furthermore, the linkage mechanism includes a connecting shaft fixedly connected to the lower end of the mounting shaft, a first mounting bearing is sleeved between the connecting shaft and the dust reduction mounting box, the lower end of the connecting shaft is fixedly connected to a connecting frame, a mounting ring is fixedly connected to the outer side of the connecting frame, the mounting ring is fixedly connected to the connecting box body, a plurality of mounting holes are evenly provided at the lower end of the connecting box body, a plurality of mounting pipes are evenly fixedly installed on the lower surface of the connecting box body, an atomizing nozzle is fixedly installed at the lower end of the mounting pipe, and an independent solenoid valve is installed on each atomizing nozzle, the dust reduction mounting box and the connecting box body, the mounting hole and the mounting pipe are interconnected, a rotating groove is provided in the mounting ring, and a rotating seat is rotatably connected in the rotating groove.
[0014] Through the above technical solution, the rotation of the installation shaft drives the connecting shaft to rotate, and the connecting shaft can transmit power to the connecting box through the action of the connecting frame, so that the atomizing nozzle on the connecting box can rotate with the rotation of the connecting shaft, and the water mist can be sprayed evenly in a circular shape.
[0015] Furthermore, the adjustable spray mechanism includes an air inlet base rotatably connected to the linkage mechanism, the lower end of the air inlet base is fixedly connected to an air inlet box, a plurality of air inlet holes are provided on the upper circumference of the air inlet box, the upper end of the air inlet base is fixedly connected to a fixed shaft, a second mounting bearing is sleeved between the outer side of the fixed shaft and the linkage mechanism, an electric fan is installed in the air inlet box, the lower end of the air inlet box is fixedly connected to a motor box, a drive motor is fixedly installed in the motor box, the output end of the drive motor is fixedly connected to a drive shaft, a drive plate is fixedly installed on the drive shaft, and the drive plate is rotatably connected to the air inlet box.
[0016] Through the above technical solution, the output end of the driving motor drives the driving plate to rotate through the driving shaft, so that the positions of the first connecting hole and the second connecting hole coincide with each other, and the electric fan will inhale a large amount of air through multiple sets of air inlet holes, and then the airflow will enter the air inlet box, and the high-speed airflow will pass through the first connecting hole and the second connecting hole into the jet duct, and then be ejected through multiple jet ducts.
[0017] Furthermore, the driving plate is evenly provided with a plurality of first connecting holes, and the lower end of the air inlet box is evenly provided with a plurality of second connecting holes. The driving plate can be adjusted by rotating at different angles to enable the first connecting holes and the second connecting holes to be connected.
[0018] Through the above technical solution, when the first connecting hole and the second connecting hole are connected, the jet pipe can form an airflow by jetting outward, which pushes the water mist generated by the atomizing nozzle to spread more evenly to the surroundings, expand the dust reduction coverage, and make the dust reduction area more comprehensive. The airflow and water mist interact with each other. On the one hand, the water mist particles and dust particles are more fully in contact and collided, increasing the probability of dust being adsorbed by the water mist; on the other hand, the airflow drives the mixture of water mist and dust to settle rapidly downward, accelerating the dust reduction speed and improving the dust reduction efficiency.
[0019] Furthermore, a plurality of jet pipes are evenly arranged at the lower end of the air inlet box, the air inlet box and the plurality of jet pipes are fixedly connected, the plurality of jet pipes and the air inlet box are interconnected, and the bending angles of the jet pipes are different.
[0020] Through the above technical solution, the airflows ejected from the jet pipes at different jet angles interact with each other to form a variable airflow field around the device. This airflow field can change the movement trajectory of dust particles in the air, increase the chance of collision between dust and water mist, and increase the probability of dust being adsorbed by water mist.
[0021] The beneficial effects of the present invention are as follows: (1) The present invention designs a matching water flow driving mechanism and a linkage mechanism. The water flow driving mechanism uses the energy of the water flow to drive the installation shaft to rotate, and converts the kinetic energy of the water flow into the mechanical energy of the installation shaft, thereby driving the connection box and multiple atomizing nozzles to rotate, effectively utilizing water flow resources, without the need for an additional power source, and reducing energy consumption and operating costs; (2) The present invention designs an adjustable spray mechanism. The jet pipe of the jet can form an airflow when the jet is ejected outward, which drives the water mist generated by the atomizing nozzle to spread more evenly around, expand the dust reduction coverage, and make the dust reduction area more comprehensive. The airflow interacts with the water mist, which makes the water mist particles and the dust particles more fully contact and collide, increasing the dust reduction area. On the other hand, the airflow drives the mixture of water mist and dust to settle rapidly downward, accelerating the dust settling speed and improving the dust settling efficiency. At the same time, the water mist generated by the atomizing nozzle will gather in some areas to form water accumulation, and the spray adjustable mechanism can blow out the gathered water mist to keep the working area relatively dry, reducing the problems of slippery ground and equipment corrosion caused by water accumulation. (3) The present invention designs jet pipes with different angles. The airflows ejected by the jet pipes at different jet angles interact with each other to form a variable airflow field around the device. This airflow field can change the movement trajectory of dust particles in the air, increase the chance of collision between dust and water mist, and increase the probability of dust being adsorbed by water mist.

The lower the center of gravity, the more stable the object, and when subjected to external force, the device is less likely to tip over or shake, thereby improving the overall stability of the device during use.
[0034] like Figures 1-4 As shown, the water flow pushing mechanism 2 includes a mounting shaft 25 rotatably connected to the dust reduction mounting box 1, and a plurality of mounting fan blades 26 are evenly fixedly installed on the circumference of the mounting shaft 25. A liquid inlet pipe 20 is fixedly installed on one side of the dust reduction mounting box 1, and a first connecting seat 21 is fixedly connected to the end of the liquid inlet pipe 20 away from the dust reduction mounting box 1. A second connecting seat 22 is fixedly installed on one side of the first connecting seat 21, and a liquid outlet pipe 24 is fixedly connected to the second connecting seat 22. The liquid outlet pipe 24 is connected to the water tank outlet pipe, and the first connecting seat 21 and the second connecting seat 22 are fixedly connected by a plurality of fixing bolts 23. The water flow pushing mechanism 2 is convenient to operate. The energy of the water flow is used to drive the installation shaft 25 to rotate, and the kinetic energy of the water flow is converted into the mechanical energy of the installation shaft 25, which in turn drives the connecting box 33 and multiple atomizing nozzles 36 to rotate, effectively utilizing the water flow resources without the need for an additional power source; the liquid inlet pipe 20 and the dust reduction installation box 1 are interconnected, and the liquid inlet channel of the liquid inlet pipe 20 is arranged in a tangent structure with the dust reduction installation box 1, so that the water flow input by the liquid inlet pipe 20 can enter the dust reduction installation box 1 through the liquid inlet, and because the liquid channel and the dust reduction installation box 1 are in a tangent structure, the water flow entering the dust reduction installation box 1 can drive the linkage mechanism 3 to rotate.
[0035] like Figure 1-Figure 7 As shown, the linkage mechanism 3 includes a connecting shaft 30 fixedly connected to the lower end of the mounting shaft 25, a first mounting bearing 39 is sleeved between the connecting shaft 30 and the dust suppression mounting box 1, a connecting frame 31 is fixedly connected to the lower end of the connecting shaft 30, a mounting ring 32 is fixedly connected to the outer side of the connecting frame 31, and the mounting ring 32 is fixedly connected to the connecting box body 33. A plurality of mounting holes 34 are evenly arranged at the lower end of the connecting box body 33, and a plurality of mounting pipes 35 are evenly fixedly installed on the lower surface of the connecting box body 33. An atomizing nozzle 36 is fixedly installed at the lower end of the mounting pipe 35. , and each atomizing nozzle 36 is installed with an independent solenoid valve. The dust suppression installation box 1 and the connecting box body 33, the installation hole 34, and the installation pipe 35 are interconnected. A rotating groove 37 is opened in the installation ring 32, and a rotating seat 38 is rotatably connected in the rotating groove 37. The rotation of the installation shaft 25 drives the connecting shaft 30 to rotate. The connecting shaft 30 can transmit power to the connecting box body 33 through the action of the connecting frame 31, so that the atomizing nozzle 36 on the connecting box body 33 can rotate with the rotation of the connecting shaft 30, and the water mist can be sprayed evenly in a circular shape.
[0036] like Figures 1-9As shown, the spray adjustable mechanism 4 includes an air inlet base 40 rotatably connected to the linkage mechanism 3, the lower end of the air inlet base 40 is fixedly connected to an air inlet box 41, and a plurality of air inlet holes 42 are provided on the circumference of the air inlet box 41. The upper end of the air inlet base 40 is fixedly connected to a fixed shaft 43, and a second mounting bearing 44 is sleeved between the outer side of the fixed shaft 43 and the linkage mechanism 3. An electric fan 45 is installed in the air inlet box 41, and the lower end of the air inlet box 41 is fixedly connected to a motor box 48. A drive motor 49 is fixedly installed in the motor box 48, and the output end of the drive motor 49 is fixedly connected to the motor box 48. A drive shaft 410 is fixedly connected to the drive shaft 410, and a drive plate 46 is fixedly installed on the drive shaft 410. The drive plate 46 is rotatably connected to the air inlet box 41. The output end of the drive motor 49 drives the drive shaft 410 to rotate. The drive shaft 410 transmits power to the drive plate 46, and then drives the drive plate 46 to rotate. When the drive plate 46 rotates, it can drive the first connecting hole 47 on the drive plate 46 to rotate. When the first connecting hole 47 rotates to coincide with the position of the second connecting hole 411, the air inlet box 41 and the jet pipe 412 are connected through the first connecting hole 47. The first connecting holes 47 and the second connecting holes 411 are connected to each other, and the electric fan 45 will inhale a large amount of air through the multiple groups of air inlet holes 42, and then the air flow will enter the air inlet box 41, and the high-speed air flow will enter the jet duct 412 through the first connecting holes 47 and the second connecting holes 411, and then be ejected through the multiple jet ducts 412; the driving plate 46 is evenly provided with multiple groups of first connecting holes 47, and the lower end of the air inlet box 41 is evenly provided with multiple groups of second connecting holes 411. The driving plate 46 can be adjusted by rotating at different angles to make the first connecting holes 47 and the second connecting holes 411 connected to each other. When the through holes 411 are interconnected and the first connecting hole 47 is interconnected with the second connecting hole 411, the jet pipe 412 can form an airflow when it ejects air outward, pushing the water mist generated by the atomizing nozzle 36 to spread more evenly around, expanding the dust reduction coverage, and making the dust reduction area more comprehensive. The airflow and water mist interact with each other, on the one hand, making the water mist particles and dust particles more fully contact and collide, increasing the probability of dust being adsorbed by the water mist; on the other hand, the airflow drives the mixture of water mist and dust to quickly settle downward, accelerating the dust reduction speed and improving the dust reduction efficiency.
[0037] like Figure 1-Figure 5 As shown, multiple groups of jet pipes 412 are evenly arranged at the lower end of the air inlet box 41, and the air inlet box 41 is fixedly connected to the multiple groups of jet pipes 412. The multiple groups of jet pipes 412 and the air inlet box 41 are interconnected, and the bending angles of the multiple groups of jet pipes 412 are different. The airflows ejected by the jet pipes 412 at different jet angles interact with each other to form a variable airflow field around the device. This airflow field can change the movement trajectory of dust particles in the air, increase the chance of collision between dust and water mist, and increase the probability of dust being adsorbed by water mist.
[0038] The working principle of this embodiment is as follows: the liquid outlet pipe 24 is connected to the water tank outlet pipe, and the water pump pumps the water in the water tank into the dust reduction installation box 1 through the liquid inlet pipe 20. After the water flows into the dust reduction installation box 1 through the liquid inlet pipe 20, the water flow will push the multiple installation blades 26 to rotate in the tangential direction, and then can push the installation shaft 25 and the linkage mechanism 3 to rotate. The setting of the rapid current mounting plate 11 can concentrate the water flow to the effective action area of the installation blades 26, so that the impact force of the water flow on the installation blades 26 is more concentrated, thereby enhancing the rotational power of the installation shaft 25. The water flows through the gap between the rapid current mounting plate 11 and the installation shaft 25 and then through the circulation groove 12 to enter the connecting box body 33, enter the installation pipe 35 through the mounting hole 34, and then is atomized and sprayed out by the atomizing nozzle 36;
[0039] At the same time, the rotation of the mounting shaft 25 drives the connecting shaft 30 to rotate, and the connecting shaft 30 can transmit power to the connecting box 33 through the action of the connecting frame 31, thereby enabling the atomizing nozzle 36 on the connecting box 33 to rotate along with the rotation of the connecting shaft 30, and the water mist can be sprayed evenly in a circular shape;
[0040] When the water mist is sprayed evenly, the drive motor 49 is started, and the output end of the drive motor 49 drives the drive shaft 410 to rotate. The drive shaft 410 transmits power to the drive plate 46, which in turn drives the drive plate 46 to rotate. When the drive plate 46 rotates, it can drive the first connecting hole 47 on the drive plate 46 to rotate. When the first connecting hole 47 rotates to a position that coincides with the second connecting hole 411, the air inlet box 41 and the jet duct 412 are connected to each other through the first connecting hole 47 and the second connecting hole 411. During actual operation, after the electric fan 45 is powered on, the electric fan 45 will inhale a large amount of air through multiple groups of air inlet holes 42, and then the airflow will enter the air inlet box 41, and the high-speed airflow will pass through the first connecting hole 47 and the second connecting hole 411 into the jet duct 412, and then be ejected through multiple jet ducts 412, thereby achieving dust reduction over a wider range.
[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
